# Stuff involving dialog
|
|
|
|
# rpardini: dialog reports what happened via nonzero exit codes.
|
|
# we also want to capture the stdout of dialog.
|
|
# this is a helper function that handles the error logging on/off and does the capturing
|
|
# then reports via exported variables, which the caller can/should test for later.
|
|
# warning: this will exit with error if stdin/stdout/stderr is not a terminal or running under CI, or if dialog not installed
|
|
# otherwise it will NOT exit with error, even if user cancelled.
|
|
# This is a boring topic, see https://askubuntu.com/questions/491509/how-to-get-dialog-box-input-directed-to-a-variable
